    RF LNA on a budget

    @brandon7861 I just received the probes, but they have a strange connector on them. Looks like a push on, but my push on isn't exactly the right size, a little too small. Would you know what connector it is? Also, this thing is tiny. I'm searching for a suitable enclosure. Do you think I...

    Interfering With Neighbors TV

    Id use rg6, I've never heard of rg57, but she may have some rg59 existing, which is much better than twin-lead.

    50 Years of Power from a Battery? Sounds good to me !

    Yeah, I think if they can put a city underground, such as the military installations I've heard about, they should put nuclear power plants underneath the earth as well, below the water table if possible. That way, if a meltdown occurs, it would be covered up and not have to worry about any...

    50 Years of Power from a Battery? Sounds good to me !

    Incoming rant. I'm guessing you live in a populated area. Speaking as a rural area representative, we don't want your nuclear power plant in our yard. That's a common opinion 'round here. What about the impact on our lives and environment? If you want nuclear power, put it on your own land. Not...

    Hi. We've been trying to reach you about your car's extended warranty.

    What would be the reaction if Hams used 11m legally using their calls.

    I understand, per ARRL, that FCC designated call signs shall not be used on 11 meter CB band. They also say that you shall not exceed 4 watt carrier, but that's often ignored. I wouldn't use my call sign on there, anyone with half a brain and easily triggered can locate you and obtain sensitive...

    10.24Mhz xtal source

    After using a few of them, and testing others, they all do work, but aren't on frequency, and one required so much added capacitance to bring it close (150hz shy) that the circuit would stop oscillating. I'm going to order some that Brandon mentioned as xtal height isn't a concern really.

    Paco V-70 VTVM info

    Thanks, that has more info than what I found. I will be satisfied with this and if I can't figure it out with this information, I don't need the thing.

    RF LNA on a budget

    Yeah, thanks Brandon, for the probe link too. I ordered 2. You know, you sound like me, but always a few steps ahead of me. I've learned a lot lately trying to keep up with you. It's been fun.

    RF LNA on a budget

    After re-reading your post, I see what you're getting at, regarding the insertion of the amp between probe impedance/resistance and the divider formed with 1M input to the FC, no longer following assumed standard formula, as if the amp wasn't there. All that acting up on the fragile circuit...

    RF LNA on a budget

    Thanks for sharing your experience, I also noted that when the probe is not connected to anything, it picks up whatever and amplifies. Nothing is perfect as you already know, and I may not get the greatest accuracy but I can get close enough for my satisfaction, knowing the limitations and...

    Old D-104 Base Mic help

    I have had luck hitting the wax with hot air, assuming the rock is still attached to the back wall. When the foil gets bent, distorted, it puts an odd or uneven tension on the rock ?yoke? inside and reheating the wax can reset its hold between the diaphragm and shaft. Sorry, I can't recall the...

    RF LNA on a budget

    If you have issues getting your >20mv scope to trigger on <20mv signals, or the 1x probe loads down the circuit causing random inaccurate readings/stalling, check this out. I saw a video on YT about this device, using it as a RF preamp and as an amp for your probes. The gain is variable...

    Strange arc welder sound in a new PC68LTX TX audio

    Brandon, I feel like I just watched some pll porn, looking into the secret, private parts of the thing, that we all knew it had, but never saw it doing it like that before. I feel dirty now, knowing how that pll gets on-and off- to make us happy. Perhaps this is porn for tech nerds. I'll see...

    RCI RT-1 MOSFETs WTF?

    Oh, that's gimmicky, but mildly interesting nonetheless. The video I saw looked like it had a pot on it, if so, could be someone else's idea to replace the resistor in that NPC deal so they can say "it's not like the regular NPC and costs more because it's better and your buddies will be...

    RCI RT-1 MOSFETs WTF?

    I see a video on yt showing someone installing one, 2 wires near the pass modulator. Interested in what's inside that thing, maybe another post instead of hijacking this one. Sorry nomad, carry on sir.

    RCI RT-1 MOSFETs WTF?

    Snap cap, idk what that device is, but I believe someone stuffed it into one of these, likely for some tacti-cool effect.

    RCI RT-1 MOSFETs WTF?

    Is that a 9mm snap cap with wires shoved in it? (Plastic cartridge for dry firing a pew pew). If not, what in the world is it?

    New guy here in search of bring back a Tram D201

    That's a beautiful radio. I'd be tickled to have one of those on the bench. I hope you find someone local, as shipping can be/often is bad on tube rigs, they don't handle those packages tenderly and I have seen\heard of tubes falling out and getting busted during shipping. Id remove the tubes...
